HOOK AND EYE.

SPECIFICATION forming part of Letters Patent No. 687,197, dated November 26, 1901.

Application filed June 21, 1901.

To all whom it may concern/.-

Be it known that I, FRANK M. CHANDLER, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and Improved Member of Hooks and Eyes, of which the following is a specification.

My invention relates to improvements in the eye member of a hook-and-eye fastening for garments, belts, surcingles, &c. It is designed for use in conjunction with hooks of the twin type, such as are commonly formed of a single strand of wire, the ends of which are bent into hook form, the central portion bent so as to place the hooks side by side, and providing an anchorage-loop and two shanks, the two hooks to operate as one hook; and it has for its object to provide an eye of simple construction that Will hold a hook without danger of accidental displacement and yet permit a quick and easy separation of the hook and eye when desired, which object I accomplish by means of a mechanism illustrated in the accompanying drawings and as hereinafter more fully pointed out.

Figure l is a perspective View of my improved eye; Fig. 2, a plan view with hook at tached; Fig. 3, a transverse section on the line a: y of Fig. 2; Fig. 4, a general view of a complete hook; Fig. 5, an edge View of a hook, and Fig. 6 a detail edge view illustrating relative positions of a hook and eye when being joined and when the hook is being cast off.

Similar letters of reference refer to similar parts throughout the several views.

My improved eye member of a hook and eye consists of a mechanism illustrated in Fig. 1, where a denotes a bar for attaching the eye to a belt or other object, I) 17 side members, and n the bow. The bow is provided midway between the side members with an inwardly-extending stem 0. This stem is of an even breadth from its base to the outer end, which latter may be either rounded or pointed, and its sides, which in use are in contact with the hooks, are parallel with each other. In breadth stem 0 may be the same as that of the space between the arches of the hook members of the double hook. The bow is further provided with a short plain projection or stop d, placed on one Serial No. 65,391. (No model.)

face of the eye in line with stem 0. This projection is in breadth equal, or nearly so, to the space between the members 9 g of the hooks where they cross the bow n of the eye and more than equal to the space at it between members j j. As will be morefully explained hereinafter, stem 0 and stop (1 together serve to retain the hook member when interlocked with the eye.

A hook for use in conj unctiou with my improvedeye member illustrated in the drawings is made of a single length of wire bent so as to provide an anchorage-loop 71 j j, the side members jj brought together, or nearly so, at h, divergent shank members 9 g, and hook terminals e e, brought together,or nearly so, at their ends, as shown in Fig. 3.

The bills in the hook members of a double hook are usually made short and require in the eye to which they are joined a means for their retention against accidental displacement. The Doolittle (patent July 27, 1897) and Law (patent January 28, 1868) devices for this purpose provide of an enlargement with reduced neck or spear-head stem placed similarly to stem 0 in my improved eye. This enlargement necessitates a forced spreading apart of the hooks over the enlargement or head in order to completely join the hook and eye.

The members 0 and d serve jointly to prevent accidental unlocking of the hook and eye. As will be seen, stem 0 occupies the widest portion of the space between the arches of the twin hooks e 6. It forms a post which the bills andarches of the hooks partly encircle, as particularly shown in Fig. 3, thus serving to resist all rotary movement of the hooks on the bow of the eye, such movement causing a spreading apart of the hooks, which spreading would be resisted by the spring action inthe shanks of the hooks. The oflice of stop cl is to prevent a forward or longitudinal sliding movement of the hooks on stem 0 toward a, which might cause a disengagement of the hook and eye. Stop (Z, projecting from how n between divergent members 9 g of hook, serves to cause a forced spreading apart by wedge action of members g g whenalongitudinal movement of those members occurs, and thus resisting serves to prevent such movement. Stop (1 does not appreciably interfere with the operation of engaging the hook and eye, which is efiected in the same manner as that of the common hook and eye. To disengage quickly, a simple rotary movement of the hook on the bow of the eye, as illustrated in Fig. 6, forces the hills e of the hook apart and causes them to pass over stem 0. Then by a quick return of the ends of the bills 8 to their normal position before reaching stop (Z the hook is automatically cast off.

Having fully described my invention, what I claim, and desire to secure by Letters Patout, is

1. An eye member of a hook and eye, comprising a frame a, b, b, n, the how 11 provided midway between side members I) b with a rearmembers of a double hook when hook and eye 30 are interlocked, substantially as set forth. FRANK M. CHANDLER.
